Notes: Posted for the curious brown purple staining upon handling (instantaneous). Makes an observable thumb or finger print.
Stain slowly spreads. After picking, the underside oxidizes (?) changing color from cream to a barely noticeable light purple color. Shelf like fungi so common here, I normally do not photograph them unless it is something interesting.

This is similar to the Ganoderma in North America going under the name Ganoderma applanatum (artists conk). I am not sure of the identity of the Asian counterpart but I think it is a separate species. Asian Ganoderma seem under represented on Mushroom observer. Very nice find, thank you for posting.

One study found a high number of the same medicinal compounds as those found in the traditional Asian reishi also occur in “Ganoderma applanatum” but it doesn’t make note of where the specimen originated that was used in the test. (Ganoderma- a therapeutic fungal biofactory 2006)

It may be interesting to look at the other ganoderma observation I made earlier this year. It was collected from the roots of a very ancient grove of oaks and camphor trees in an equally ancient archeological site/park. I did not not know at the time of the valuable medicinal properties/ the association with “reshi” fungus that is. If this one is ganoderma, it is not of the “red” variety I assume, curious as to whether it also may have medicinal properties, or is it just the “red” variety. Ganoderma is very popular here as an herbal remedy/elixer.
